Abstract

The invention discloses a treatment system for removing organic phosphates in electroplating wastewater, which comprises a water collecting well, a coarse rack, a primary sedimentation tank, a pH value regulation tank, a mucus protein-phosphate adsorption reactor, a centrifugal separator, a pH value secondary regulation tank, an aeration oxidation tank, a secondary sedimentation tank and a pure water tank. The system creatively utilizes a rotation net tank filled with Chinese yam and taro chips as a surface contact reaction medium; when the organic-phosphate-containing electroplating wastewater contacts the surface contact reaction medium, the organic phosphates in the wastewater and the mucus proteins are subjected to adsorption reaction under the adsorption actions of the rich mucus proteins contained in the Chinese yam and taro so as to generate a phosphate complex. The complex is insoluble in water, and can be removed by the centrifugal separation operation. Meanwhile, the Chinese yam, taro and the like belong to common crops, and can greatly lower the material cost for wastewater treatment when being used as low-value consumables.

Description

technical field [0001] The invention relates to a treatment system for removing organic phosphate in electroplating wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] In the electroplating industry and metal surface treatment industry, phosphate or polyphosphate is commonly used as a chemical reaction catalyst. Phosphorus is one of the elements necessary for biological growth. However, if the content of phosphate (especially organic phosphate) in water is too high (more than 0.2mg / L), it can cause excessive algae reproduction, and even reach a harmful level (called eutrophication), resulting in reduced transparency of lakes and rivers. , the water quality deteriorates; at the same time, the toxicity of organophosphates cannot be ignored, which will cause irreparable impacts on the ecological environment. [0003] At present, the common wastewater phosphorus removal technologies in my country include: (1...
